Front

What does Newton's First Law of Motion state about a moving object not acted on by an unbalanced force?

Back

A moving object will remain in motion.

Front

What is Newton's First Law commonly known as?

Back

The Law of Inertia.

Front

If you push on a stationary object and it doesn't move, what can you say about the force it exerts back on you?

Back

The object exerts an equal force back on you (Newton's Third Law).

Front

What unit is used to measure force?

Back

Newtons (N).

Front

True or False: An object's inertia is affected by its mass.

Back

True.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

Give an example of inertia in everyday life.

Back

A book resting on a table will remain at rest until someone picks it up.

Front

What happens to a moving car if no forces act on it?

Back

It will continue to move at a constant speed in a straight line.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate or change its motion.
